Why do you use quad cable in your OpticalCon Duo assemblies?

We make our OpticalCon Duo assemblies with quad cable. Here is our thinking: The symmetrical, square, quad configuration actually protects the fibres from damage by crushing , much better than two fibres, where one often ends up on top of the other. Also, the actual extra fibres are not very expensive, the least costly part of the cable, so represent a small additional cost over dual fibre.
